Health insurance and utilization of medical care for children with special health care needs

Tackling access and payer barriers for growth hormone therapy in Saudi Arabia: a consensus statement for the Saudi Working Group for Pediatric Endocrinology

Prompt diagnosis and early treatment are key goals to optimize the outcomes of children with growth hormone deficiency (GHD) and attain the genetically expected adult height. Nonetheless, several barriers can hinder prompt diagnosis and treatment of GHD, including payer-related issues. In Saudi Arabia, moderate-to-severe short stature was reported in 13.1 and 11.7 % of healthy boys and girls, respectively. Several access and payer barriers can face pediatric endocrinologists during the diagnosis and treatment of GHD in Saudi Arabia. Insurance coverage policies can restrict access to diagnostic tests for GHD and recombinant human growth hormone (rhGH) due to their high costs and lack of gold-standard criteria. Some insurance policies may limit the duration of treatment with rhGH or the amount of medication covered per month. This consensus article gathered the insights of pediatric endocrinologists from Saudi Arabia to reflect the access and payer barriers to the diagnostic tests and treatment options of children with short stature. We also discussed the current payer-related challenges endocrinologists face during the investigations of children with short stature. The consensus identified potential strategies to overcome these challenges and optimize patient management.

Imprisonment, opioids and health care reform: The failure to reach a high-risk population

The 2014 National Research Council report on American incarceration optimistically anticipated the Affordable Care Act (ACA) would be "a turning point in the nation's health care, and … will provide unprecedented access to care for many people being released from correctional facilities." However, the ACA was not designed to proactively respond to risks associated with prisoner re-entry into society. Our overarching hypothesis is that unmet health needs among previously incarcerated adults can be more fully understood by analyzing how un-prescribed use of drugs, such as opioids, is associated with economic and health problems and health care un-insurance that in turn results in exclusion from needed health care services. Using several waves of the National Longitudinal Study of Adolescent to Adult Health conducted before and after passage and implementation of ACA, our analysis indicates that the above risk factors nearly fully mediate the association between previous incarceration and failure to receive needed health care. We argue that these factors are likely intensified by a reactive approach to health care reform that not only fails to cover many former prisoners, but also is lacking in sufficient outreach programming, and as such is insufficient for adults with health problems and limited economic resources - especially those using un-prescribed opioids. Future work should address the capacity of more proactively organized public health programs to expand coverage to previously incarcerated populations - including un-prescribed opioid users - and thereby reduce their health risks and vulnerability to repeated exposure to law enforcement surveillance and criminal punishment.

Maternal imprisonment, economic marginality, and unmet health needs in early adulthood

There is relatively little research on access to the health care needed by children whose mothers have been incarcerated, and even fewer studies of how effects of lack of access continue and cumulate as these children transition from living with parents, parent surrogates, or foster care into adulthood. We find in a nationally representative U.S. panel study (n=9418 participants from 1995 to 2007-2008 in the National Longitudinal Study of Adolescent and Adult Health) that young adult children of incarcerated mothers are less likely to receive the health care they need. These effects hold in models that take into account covariates and receipt of health care in the past, a useful control for unmeasured heterogeneity. In this analysis for 2007-2008, economic marginality mediates maternal incarceration on young adult unmet health care needs. Health insurance mediates a smaller portion of this effect. The findings of this research provide important bench marks for assessing the effects of the 2010 passage and the 2013 implementation of the Affordable Care Act [ACA], as well as prospective efforts to change or repeal the ACA.

Medical home and pediatric primary care utilization among children with special health care needs

INTRODUCTION

The medical home model seeks to improve health care delivery by enhancing primary care. This study examined the relationship between the presence of a medical home and pediatric primary care office visits by children with special health care needs (CSHCN) using the data from 2005-2006 National Survey of Children with Special Healthcare Needs.

METHOD

Survey logistic regression was used to analyze the relationship.

RESULTS

When CSHCN age, gender, ethnicity/race, functional status, insurance status, household education, residence, and income were included in the model, CSHCN with a medical home were 1.6 times more likely to have six or more annual pediatric primary care office visits than were children without a medical home [odds ratio = 1.60, 95% confidence interval = (1.47, 1.75)]. Female CSHCN, younger CSHCN, children with public health insurance, children with severe functional limitations, and CSHCN living in rural areas also were more likely to have a larger number of visits.

DISCUSSION

By controlling for child sociodemographic characteristics, this study provides empirical evidence about how medical home availability affects primary care utilization by CSHCN.

Access to health care and heavy drinking in patients with diabetes or hypertension: implications for alcohol interventions

Supported by a National Institute of Alcoholism and Alcohol Abuse grant, this study examined associations between health care access and heavy drinking in patients with hypertension and diabetes. Using a sample of 7,428 US adults from the 2007 National Health Interview Survey data, multivariate logistic regressions were performed. Better access to health care, as indicated by regular source of care and frequent use of primary care, was associated with reduced odds of heavy drinking. Alcohol interventions may be more effective if targeted at patients with chronic conditions adversely affected by drinking. Future research needs to investigate factors facilitating such interventions.

Children with special health care needs: how immigrant status is related to health care access, health care utilization, and health status

To compare health care access, utilization, and perceived health status for children with SHCN in immigrant and nonimmigrant families. This cross-sectional study used data from the 2003 California Health Interview Survey to identify 1404 children (ages 0-11) with a special health care need. Chi-square and logistic regression analyses were used to examine relations between immigrant status and health access, utilization, and health status variables. Compared to children with special health care needs (CSHCN) in nonimmigrant families, CSHCN in immigrant families are more likely to be uninsured (10.4 vs. 4.8%), lack a usual source of care (5.9 vs. 1.9%), report a delay in medical care (13.0 vs. 8.1%), and report no visit to the doctor in the past year (6.8 vs. 2.6%). They are less likely to report an emergency room visit in the past year (30.0 vs. 44.0%), yet more likely to report fair or poor perceived health status (33.0 vs. 16.0%). Multivariate analyses suggested that the bivariate findings for children with SHCN in immigrant families largely reflected differences in family socioeconomic status, parent's language, parental education, ethnicity, and children's insurance status. Limited resources, non-English language, and limited health-care use are some of the barriers to staying healthy for CSHCN in immigrant families. Public policies that improve access to existing insurance programs and provide culturally and linguistically appropriate care will likely decrease health and health care disparities for this population.

Maternal health and child asthma health services use

The primary purpose of this pilot study was to examine the influence of maternal health status on health services use in children with the diagnosis of asthma. A secondary purpose was to assess both preventive and illness-related child health services use patterns. Fifty-two asthmatic children and 43 mothers met the inclusion criteria. The majority of mothers (72%, n = 31/43) rated their own overall health as good to excellent. Eighty-six percent (n = 38/44) of the children had a medical home, 20% had peak flow meters, 26% had been to see a specialist, and 4% were currently under the care of a specialist. This pilot study raises important questions about the influence of maternal health on child health services use patterns for asthmatic children from low-income families. Understanding the influence of maternal health on health-seeking patterns for children with asthma is important for nursing intervention.

Healthcare utilization and expenditures for low income children with sickle cell disease

BACKGROUND

While multiple studies have examined the healthcare burden of sickle cell disease (SCD) in adults, few have specifically focused on healthcare utilization and expenditures in children. The objective of this study was to characterize the healthcare utilization and costs associated with the care of low-income children with SCD in comparison to other children of similar socioeconomic status.

PROCEDURE

For the study period, 2004-2007, we conducted a retrospective, cross-sectional descriptive analysis of administrative claims data from a managed care plan exclusively serving low-income children with Medicaid and the State Children's Health Insurance Plan (SCHIP). Patient demographics, continuity of insurance coverage, healthcare utilization, and expenditures were collected for all children enrolled with SCD and the general population within the health plan for comparison.

RESULTS

On average, 27% of members with SCD required inpatient hospitalization and 39% utilized emergency care in a given calendar year. Both values were significantly higher than those of the general health plan population (P < 0.0001). Across the study period, 63% of members with SCD averaged one well child check per year and 10% had a minimum of one outpatient visit per year to a hematologist for comprehensive specialty care.

CONCLUSIONS

Low-income children with SCD demonstrate significantly higher healthcare utilization for inpatient care, emergency center care, and home health care compared to children with similar socio-demographic characteristics. A substantial proportion of children with SCD may fail to meet minimum guidelines for outpatient primary and hematology comprehensive care.

The influence of health insurance on parent's reports of children's unmet mental health needs

OBJECTIVE

The purpose of this study was to examine the prevalence of unmet mental health needs in children identified by parents as having long-term emotional and behavioral problems, to identify the characteristics of these children, and to evaluate the influence of health insurance status and type on the odds of reporting unmet mental health needs.

METHODS

We used the National Survey of Children with Special Health Care Needs (NSCSHCN) to estimate the prevalence of unmet mental health needs among children with long-term emotional/behavioral conditions. Using logistic regression models, we also assessed the independent impact of insurance status and type on unmet needs.

RESULTS

Analyses indicated that of the nearly 67% of children who needed mental health care or counseling in the previous 12 months, 20% did not receive it. Moreover, parents of uninsured children were more likely to report unmet mental health needs than insured children. Parents of children covered by public health insurance programs (Medicaid, Children Health Insurance Program-CHIP, Title V, Military, Native American) were less likely to report unmet mental health needs than those with children covered by private health insurance plans.

CONCLUSION

Results from this study suggest a need for expansion of health insurance coverage to children especially those with long-term mental health conditions. It also suggests a need for parity between mental and physical health benefits in private health insurance.

Healthcare needs and healthcare satisfaction from the perspective of parents of children with chronic conditions: the DISABKIDS approach towards instrument development

AIM

Increasingly, families' perspectives are taken into account in the appraisal of health services. The objective of this study was to cross-culturally analyse concepts related to healthcare needs, healthcare utilization and the appraisal and satisfaction with care of parents of children with chronic conditions with the aim of developing a cross-cultural measure.

METHODS

Several approaches were employed in the study: (i) a deductive approach integrating existing measurements; and (ii) an inductive approach based on focus groups. Focus groups were conducted in seven countries with mothers and fathers as well as their children with seven different chronic conditions, and qualitatively analysed.

RESULTS

As a result of an evaluation of the different existing methodological approaches, the basic structural components were identified: healthcare needs, the receipt of services, problems with receiving services as well as the appraisal of and satisfaction with the quality of care. While items referring to existing healthcare services were primarily derived by the work of an expert group, items related to quality of care and satisfaction with services mainly evolved from the focus group work. From the focus groups, 367 statements were extracted, which were further processed in a Q-sort rating by a multinational expert group in order to identify domains and salient items. The draft questionnaire to be pilot tested cross-nationally consisted of 101 items which were reduced on the basis of psychometric findings.

CONCLUSION

On the basis of results of focus groups and existing evidence, a comprehensive measure should be employed in paediatric health services research including structural, process and outcome parameters of care from the perspective of parents.

Role of insurance for children with special health care needs: a synthesis of the evidence

OBJECTIVE

Children with special health care needs constitute a particularly vulnerable subpopulation of children. Health insurance coverage has the potential to enhance access to care and improve the quality of life for these children while protecting their families from financially burdensome health care expenses. The purpose of this review is to assess and synthesize recent research in the peer-reviewed literature pertaining to the role of insurance for children with special health care needs. A marked increase in the volume of research on this topic makes this an opportune time to summarize these contributions and begin the process of formalizing an evidence base that can inform health policy decisions. Our intention is to further the evidence base by providing a literature-driven assessment of the role of health insurance in influencing access, utilization, satisfaction, quality, expenditures, and health outcomes for children with special health care needs.

METHODS

A systematic literature review was conducted on the effects of insurance status, insurance type, and insurance features on access, utilization, satisfaction, quality, expenditures, and health status.

RESULTS

The strongest evidence emerged for the positive effects of insurance on access and utilization. Limited evidence on the effect of insurance on satisfaction with care showed improved satisfaction ratings for the insured. The studies with findings relevant to out-of-pocket expenditures for insured versus uninsured children with special health care needs all found significantly higher out-of-pocket burden and financial problems among the uninsured. Evidence was mixed for the effects of insurance type (public or private) and insurance characteristics (eg, managed care or fee-for-service payment mechanisms) on outcomes. None of the studies that we reviewed attempted to assess the impact of health insurance on health outcomes.

CONCLUSIONS

Our review of the literature found plentiful evidence demonstrating the positive and substantial impact of insurance on access and utilization. There also is clear evidence that insurance protects families against financially burdensome expenses. The evidence is less conclusive for satisfaction and quality and is nonexistent for health status. These latter outcomes should be the focus of future studies.

Quality-of-care indicators for the neurodevelopmental follow-up of very low birth weight children: results of an expert panel process

OBJECTIVE

To develop a set of quality indicators for the neurodevelopmental follow-up care of very low birth weight (VLBW; <1500 g) children.

METHODS

We reviewed the scientific literature on predictors of neurodevelopmental outcomes for VLBW children and the clinical practice guidelines relevant to their care after hospital discharge. An expert panel with members nominated by the American Academy of Pediatrics, the National Institute of Child Health and Human Development, the Vermont Oxford Network, and the California Children's Service was convened. We used a modified Delphi method to evaluate and select the quality-of-care indicators.

RESULTS

The panel recommended a total of 70 indicators in 5 postdischarge follow-up areas: general care; physical health; vision, hearing, speech, and language; developmental and behavioral assessment; and psychosocial issues. Of these, 58 (83%) indicators were in preventive care, 5 (7%) were in acute care, and 7 (10%) were in chronic care.

CONCLUSION

The quality indicators cover follow-up care for VLBW infants with various medical conditions. Given the elevated rates of long-term neurodevelopmental disabilities and the potential impact of poor health care, this new set of indicators provides an opportunity to assess and monitor the quality of follow-up care with the ultimate aim of improving the quality of care for this high-risk population.

Factors associated with age of diagnosis among children with autism spectrum disorders

OBJECTIVE

Early diagnosis of children with autism spectrum disorders (ASD) is critical but often delayed until school age. Few studies have identified factors that may delay diagnosis. This study attempted to identify these factors among a community sample of children with ASD.

METHODS

Survey data were collected in Pennsylvania from 969 caregivers of children who had ASD and were younger than 21 years regarding their service experiences. Linear regression was used to identify clinical and demographic characteristics associated with age of diagnosis.

RESULTS

The average age of diagnosis was 3.1 years for children with autistic disorder, 3.9 years for pervasive developmental disorder not otherwise specified, and 7.2 years for Asperger's disorder. The average age of diagnosis increased 0.2 years for each year of age. Rural children received a diagnosis 0.4 years later than urban children. Near-poor children received a diagnosis 0.9 years later than those with incomes >100% above the poverty level. Children with severe language deficits received a diagnosis an average of 1.2 years earlier than other children. Hand flapping, toe walking, and sustained odd play were associated with a decrease in the age of diagnosis, whereas oversensitivity to pain and hearing impairment were associated with an increase. Children who had 4 or more primary care physicians before diagnosis received a diagnosis 0.5 years later than other children, whereas those whose pediatricians referred them to a specialist received a diagnosis 0.3 years sooner.

CONCLUSION

These findings suggest improvements over time in decreasing the age at which children with ASD, especially higher functioning children, receive a diagnosis. They also suggest a lack of resources in rural areas and for near-poor families and the importance of continuous pediatric care and specialty referrals. That only certain ASD-related behaviors, some of which are not required to satisfy diagnostic criteria, decreased the age of diagnosis suggests the importance of continued physician education.

Continuity of Health Insurance Coverage for Children with Special Health Care Needs

OBJECTIVES

To assess the continuity of health insurance coverage and its associated factors for children with special health care needs (CSHCN).

METHODS

Logistic regression and proportional hazard models were estimated on monthly insurance enrollment for 5594 children in the 1996 Medical Expenditure Panel Survey. CSHCN were identified using a non-categorical approach. Stratified analyses were conducted to determine whether any characteristics differentiated the effects of CSHCN status on children's coverage.

RESULTS

In 1996, more than 8% of CSHCN were uninsured for the entire year. For those who were insured in January 1996, 14% lost their coverage by December 1996. CSHCN were more likely than other children to be insured (92% vs. 89%), mainly due to their better access to public insurance (35% vs. 23%). Conversely, CSHCN were less likely than other children to stay insured if they were school-aged, non-Hispanic White, from working, low-income families or the US Midwest region. Higher parental education improved health insurance enrollment for CSHCN, whereas higher family income or having activity limitations protected them from losing coverage. Regardless of CSHCN status, being publicly insured was associated with a higher risk of losing coverage for children.

CONCLUSIONS

Despite increased health care needs, a considerable proportion of CSHCN is unable to access or maintain coverage. Compared to other children, CSHCN are more likely to have coverage but no more likely to stay insured. Improving continuity of coverage for publicly insured children is needed, especially CSHCN who are more likely to obtain their coverage through public programs.

Insurance gaps among vulnerable children in the United States, 1999-2001

OBJECTIVE

To quantify the number of children who experience gaps in insurance coverage and to determine whether vulnerable subgroups of children experience noteworthy lapses in insurance coverage.

METHODS

We analyzed nationally representative data from 24,149 children sampled in the 1999-2001 Medical Expenditure Panel Survey linked to the 1997-1999 National Health Interview Survey. Vulnerable subgroups of children included children with chronic conditions, those from ethnic/racial minorities, and those living in poverty. On the basis of cumulative annual monthly insurance coverage status, each child fell into 1 of 3 groups: continuous coverage, uninsured, or gaps in coverage. Using SAS-callable SUDAAN, we conducted multivariate ordinal logistic regression model to quantify the likelihood of having gaps in coverage for vulnerable subgroups of children.

RESULTS

From 1999 to 2001, we found that >9 million American children annually had gaps in coverage and that 5 to 6 million children annually were uninsured for the entire year. Sixty percent of children experienced gaps of at least 4 months, and >40% of all publicly and privately insured children had coverage gaps. After accounting for relevant covariates, children with chronic conditions were just as likely as other children to have gaps in coverage or be uninsured; Hispanic children were most likely to have insurance gaps or be uninsured; and children from poor and near-poor families were 4 to 5 times more likely to have lapsed coverage than children from high-income families. Poverty and maternal education were the strongest factors associated with lapsed coverage.

CONCLUSIONS

Unstable health insurance is an underrecognized problem for children, including those with chronic conditions. Because unstable insurance coverage can lead to inadequate health care utilization and poor child health outcomes, strategies to promote stable insurance coverage merit serious consideration.

Economic impact on families caring for children with special health care needs in New Hampshire: the effect of socioeconomic and health-related factors

OBJECTIVES

To describe the economic impact on families of caring for children with special health care needs (CSHCN), and to determine the relative contributions of socioeconomic and health-related factors to these impacts on families in the State of New Hampshire.

METHODS

Seven hundred and fifty families with CSHCN in New Hampshire were interviewed in the National Survey of Children with Special Health Needs. Among respondents with CSHCN, univariate and bivariate analyses were conducted to examine economic impact and independent factors (income, insurance type, and impact of condition). Multiple logistic and linear regression models were used to examine relationships between impact and independent factors, controlling for race/ethnicity.

RESULTS

Compared to typical children, CSHCN were more likely to have public insurance (12% and 21%, respectively) and less likely to live in higher income families (56% and 48%, respectively). Among CSHCN, nearly one-quarter were greatly affected by their condition, 31% had inadequate insurance, families of 21% had financial problems, parents of 27% had to cut work hours, and almost 15% needed professional care coordination. Adjusting for other factors in regression models, the impact of the condition was associated with all measures of impact, insurance type was associated with out-of-pocket costs, and income was associated with the total number of impacts. Parents of children who are usually or always affected by their conditions were 14 times more likely than those who are never affected to need care coordination.

CONCLUSION

A family's need for support services, and particularly for care coordination, may depend less on the family's means than on the impact of their child's condition.

Utilization and costs for children who have special health care needs and are enrolled in a hospital-based comprehensive primary care clinic

OBJECTIVE

When deciding how much hospital resources should be allocated to comprehensive primary care clinics for children with multisystem disorders, it is important to consider all of the non-primary care revenue streams associated with these children as well as the effects of a comprehensive primary care program on access and quality. The objectives of this study were, first, to determine costs as well as the payments associated with hospital ambulatory and inpatient services for children with multisystem disorders followed by a comprehensive primary care clinic; and, second, to determine the effect of enrollment in a hospital-based comprehensive primary care clinic on ambulatory and inpatient utilization patterns and expenditures for children with multisystem disorders.

METHODS

The study population for the payment analysis consisted of 1012 children of all ages who were seen in the Special Primary Care Clinic (SPCC) in 2001. For these children, outcomes included direct costs, total (direct plus allocated overhead) costs, and payments per patient per 365 days after their first SPCC visit in 2001. A total of 175 of these patients were 4 years of age or older and had no SPCC visit before their first visit in 2001. We compared utilization and expenditures for the 175 children during the year before enrollment in SPCC with those in the year after enrollment. The Children's Hospital administrative database was used to document direct costs, total costs, and payments by type of service for 365 days after an index visit. Ambulatory services included medical and surgical ambulatory, inpatient, emergency department (ED), and ancillary services. We determined the proportion of children who had visits; the visit rates per 100 child-years; and the average total and direct costs per visit, per child with a visit, and per child-year. Inpatient services data included non-intensive care and intensive care hospitalization rates per 100 child-years; the proportion of children hospitalized; their average length of stay; and the average total and direct costs per hospitalization, per patient hospitalized, and per child-year of total patients in the cohort.

RESULTS

For 1012 children who were seen in SPCC in 2001, the hospital overall loss per child-year was $956. The loss per child-year for outpatient services was $1554. This loss was partially offset by a gain from inpatient services of $598. For the 175 patients for whom data were available to compare costs before and after enrollment in the SPCC, there were no significant differences in hospitalization or in direct costs per patient for patients who were hospitalized. The average length of non-intensive care stay was lower after enrollment (4.8 vs 11.7). In the surgical specialty analysis, children were more likely to see a surgeon after enrollment (41% vs 21%) and had a higher rate of visits per 100 child-years (102.3 vs 51.4). Differences in medical subspecialty, ancillary, and ED services did not achieve statistical significance.

CONCLUSION

This study suggests that children with multisystem disorders are medically fragile and require frequent hospitalizations and ED visits even with improved primary care. Enrollment in a comprehensive primary care program was associated with a decreased length of stay for non-intensive care hospitalizations and with increased use of surgical services.

Race/ethnicity and insurance status as factors associated with ADHD treatment patterns

Using data from the 1997-2000 Medical Expenditure Panel Survey (MEPS), disparities in different stages of attention-deficit/hyperactivity disorder (ADHD) health care were investigated, from initial detection to follow-up physician visits and psychotherapy appointments. Differences in ADHD diagnoses, stimulant usage, and health-care visits were examined by age, race/ethnicity, region, and type of insurance. Major significant findings were: (1) children without insurance had lower levels of care in all stages relative to children with insurance, (2) Hispanic-American and African-American children were less likely to be diagnosed with ADHD by parent report than were white American children, and (3) African-American youths with ADHD were less likely to initiate stimulant medication relative to white American children. Implications for expanding childhood health insurance coverage, and for future work on minority mental health care in regard to ADHD, are discussed.

Generational differences in U.S. public spending, 1980-2000

The balance between spending on children and spending on the elderly is important in evaluating the allocation of public welfare spending. We examine trends in public spending on social welfare programs for children and the elderly during 1980-2000. For both groups, social welfare spending as a percentage of gross domestic product changed little, even during the economic expansions of the 1990s. In constant dollars, the gap in per capita social welfare spending between children and the elderly grew 20 percent. Unlike spending for programs for the elderly, spending for children's programs suffered during recessions. Public discussion about the current imbalance in public spending is needed.

Insurance for children with special health care needs: patterns of coverage and burden on families to provide adequate insurance

OBJECTIVE

To update national estimates of insurance coverage for children with special health care needs (CSHCN) to reflect better the current economic and policy environment and to examine the burden on families and adequacy of coverage.

METHODS

I analyzed data on children who were aged 0 to 17 and included in the sample child files of the 2000 and 2001 National Health Interview Survey (NHIS). CSHCN were identified using a noncategorical approach. Various measures of insurance coverage type, premium contributions, unmet need for care, and out-of-pocket spending were compared for CSHCN and children without special needs across all incomes and stratified by poverty status.

RESULTS

Compared with other children, CSHCN had higher rates of public insurance (29.8% vs 18.5%), lower rates of private insurance (62.5% vs 69.1%), and a smaller percentage without insurance (8.1% vs 11.5%). More than 13% of low-income CSHCN were uninsured. Most (78.1%) families of CSHCN contributed to private insurance premiums. Family premium contributions for employer-sponsored insurance plans averaged 2058 dollars, or 4.4% of income; premiums for private nongroup insurance were higher (3593 dollars) and consumed a larger percentage of income (6.6%). For children with insurance, rates of unmet need for specific services were relatively low, suggesting that insurance coverage was adequate. However, almost 20% of low-income CSHCN experienced some form of unmet need and of out-of-pocket spending was significantly higher for families with CSHCN compared with those without CSHCN.

CONCLUSIONS

CSHCN are more likely to have insurance coverage, but among low-income CSHCN, lack of insurance remains a problem. In addition, the burden on families of CSHCN to provide insurance is greater, yet coverage purchased is not always adequate to meet the needs of many children and places addition burdens on families to pay directly for care.

Parents' Reports of Barriers to Care for Children With Special Health Care Needs: Development and Validation of the Barriers to Care Questionnaire

OBJECTIVE

To describe the development and validation of the Barriers to Care Questionnaire (BCQ).

METHODS

The 39-item BCQ was developed through review of the literature, focus groups, and cognitive interviews of Spanish- and English-speaking parents of children with chronic health conditions. Barriers to care are conceptualized as a multidimensional construct consisting of pragmatics, health knowledge and beliefs, expectations about care, skills, and marginalization. The BCQ was field tested in 3 samples of children with special health care needs (CSHCN).

RESULTS

Response rate for the field test was 77.2%. There were minimal missing data (0.08%), no floor effects, and minimal ceiling effects (3.8%, total scale). Internal consistency reliability (alpha) for the BCQ total scale was.95 and subscale alpha ranged from.75 to.91. The BCQ total scale and subscales correlated in the expected direction with validated measures of primary care characteristics and health-related quality of life. BCQ scores were higher (fewer barriers) for children with a primary care physician and for those who reported no problems getting care or foregone care.

CONCLUSION

The BCQ is a feasible, reliable, and valid instrument for measuring barriers to care for CSHCN. Its use may inform efforts to support consumer choice, enhance provider accountability, and spur quality improvement.

Health literacy and use of outpatient physician services by Medicare managed care enrollees

OBJECTIVE

To determine whether inadequate functional health literacy adversely affects use of physician outpatient services.

DESIGN

Cohort study.

SETTING

Community.

PARTICIPANTS

New Medicare managed care enrollees age 65 or older in 4 U.S. cities (N = 3,260).

MEASUREMENTS AND MAIN RESULTS

We measured functional health literacy using the Short Test of Functional Health Literacy in Adults. Administrative data were used to determine the time to first physician visit and the total number of visits during the 12 months after enrollment. The time until first visit, the proportion without any visit, and adjusted mean visits during the year after enrollment were unrelated to health literacy in crude and multivariate analyses. Participants with inadequate and marginal health literacy were more likely to have an emergency department (ED) visit than those with adequate health literacy (30.4%, 27.6%, and 21.8%, respectively; P =.01 and P <.001, respectively). In multivariate analysis, the adjusted relative risk of having 2 or more ED visits was 1.44 (95% confidence interval, 1.01 to 2.02) for enrollees with marginal health literacy and 1.34 (1.00 to 1.79) for those with inadequate health literacy compared to participants with adequate health literacy.

CONCLUSIONS

Inadequate health literacy was not independently associated with the mean number of visits or the time to a first visit. This suggests that inadequate literacy is not a major barrier to accessing outpatient health care. Nevertheless, the higher rates of ED use by persons with low literacy may be caused by real or perceived barriers to using their usual source of outpatient care.

Mental health services use among school-aged children with disabilities: the role of sociodemographics, functional limitations, family burdens, and care coordination

OBJECTIVE

To examine the use of mental health services and correlates of receiving services among community-dwelling children with disabilities, ages 6 to 17 years.

STUDY DESIGN

Data are from the 1994 and 1995 National Health Interview Survey Disability Supplements (NHIS-D), conducted by the National Center for Health Statistics. The study sample is 4,939 children with disabilities, representing an estimated eight million children with disabilities nationwide. Parents of children under 16 years of age reported (17-year-olds self-reported) on health, emotional and behavioral problems, mental health services use, and who, if anyone, coordinated the child's health care.

PRINCIPAL FINDINGS

Among disabled children with poor psychosocial adjustment (11.5 percent), only 11.8 percent received mental health services in the past year. Multivariate logistic regression analysis showed service use was associated with poor psychosocial adjustment; communication, social, and learning-related functional impairments; public health insurance; and financial family burdens. Younger and black disabled children were less likely to receive mental health services. The odds of service use were greater with the involvement of a health professional in coordinating care, in contrast to no one or family only. Moreover, children with disabilities were more likely to use outpatient mental health services if their care was jointly coordinated by a family member and a health professional, compared to a health professional working alone. In contrast to inpatient and outpatient care, race and family burden were not associated with the likelihood of mental health counseling in special education school settings.

CONCLUSIONS

Findings indicate that only two in five disabled children with poor psychosocial adjustment receive mental health services. Differences by age, race, and insurance coverage suggest that inequalities to access exist. However, the school setting may be one in which some barriers to mental health services for disabled children are reduced. The study also shows that the involvement of health professionals in care coordination is associated with greater access to mental health care for disabled children. These findings underscore the importance of engaging both health care professionals and the family in the care process.

Access to specialty medical care for children with mental retardation, autism, and other special health care needs

Access to specialty medical care among children with mental retardation, autism, or other types of special health care needs was examined. Results from a national survey indicate that over a third of the children with autism, over a fifth with mental retardation, and over a fifth with other types of special health care needs had problems obtaining needed care from specialty doctors in the preceding year. The most common problems included getting referrals and finding providers with appropriate training. Children with unstable health conditions, autism, or those whose parent was in poor health were at greater risk for problems. Primary Medicaid coverage and public secondary health coverage were associated with fewer access problems. Implications for health services for children with special health care needs are discussed.

Utilization of medical and health-related services among school-age children and adolescents with special health care needs (1994 National Health Interview Survey on Disability [NHIS-D] Baseline Data)

OBJECTIVE

To determine how sociodemographic factors and type of insurance influence use of medical and health-related services by children with special health care needs (CSHCN), after controlling for need.

METHODS

A cross-sectional analysis of 1994 National Health Interview Disability Survey was conducted. Children between 5 and 17 years were identified as chronically ill according to the Questionnaire for Identifying Children with Chronic Conditions (n = 3061). Independent variables included child and family characteristics categorized as predisposing, enabling, and need. Dependent variables included use of 4 medical or 7 health-related services.

RESULTS

Most children (88.7%) had seen a physician; 23.9% had an emergency department visit, 11.4% had a mental health outpatient visit, and 6.4% were hospitalized. Health-related service use ranged from <5.0% (transportation and social work) to 65.1% (medical care coordination); 20% to 30% of children used the remaining services (therapeutic, assistive devices, nonmedical care coordination, housing modifications). In fully adjusted logistic models, children with public insurance were significantly more likely than privately insured children to use 2 of the 4 medical services and 5 of the 7 health-related services. Non-Hispanic black children and children from less educated families were significantly less likely to use many of the services examined.

CONCLUSIONS

In 1994, factors in addition to need influenced medical and health-related service use by CSHCN. Differences in the scope of benefits covered by public insurance compared with private insurance may influence utilization of medical and especially health-related services. Attention is needed to ensure that CSHCN who are racial/ethnic minorities or are from less educated families have access to needed services. Future studies should determine whether these patterns have changed over time.

Parents' perceptions of pediatric primary care quality: effects of race/ethnicity, language, and access

OBJECTIVE

To examine the effects of race/ethnicity, language, and potential access on parents' reports of pediatric primary care experiences.

DATA SOURCES/STUDY SETTING

Primary survey data were collected (67 percent response rate) from 3,406 parents of students in kindergarten through sixth grade in a large urban school district in California during the 1999-2000 school year.

DATA COLLECTION

The data were collected by mail, telephone, and in person. Surveys were administered in English, Spanish, Vietnamese, and Tagalog.

STUDY DESIGN

Data were analyzed using multiple regression models. The dependent variable was parents' reports of primary care quality, assessed via the previously validated Parents' Perceptions of Primary Care measure (P3C). The independent variables were race/ethnicity, language, and potential access to care (insurance status, presence of a regular provider of care), controlling for child age, gender, and chronic health condition status, and mother's education.

PRINCIPAL FINDINGS

Parents' reports of primary care quality varied according to race/ethnicity, with Asian and Latino parents reporting lower P3C scores than African Americans and whites. In multivariate analyses, both language and potential access exerted strong independent effects on primary care quality, reducing the effect of race/ethnicity such that the coefficient for Latinos was no longer significant, and the coefficient for Asians was much smaller, though still statistically significant.

CONCLUSIONS

To reduce racial/ethnic disparities in primary care, attention should be paid both to policies aimed at improving potential access and to providing linguistically appropriate services.

Racial and ethnic disparities in access to care for children with special health care needs

OBJECTIVE

Numerous studies have examined racial and ethnic differences in access to and utilization of health services. However, few studies have addressed these issues with respect to children with special health care needs. This study examines whether disparities in access and utilization are present among black, white, and Hispanic children identified as having special health care needs.

METHODS

We analyzed data on 57 553 children younger than 18 years old included in the 1994-95 National Health Interview Survey on Disability. Of these, 10 169, or 17.7% of the sample, were identified as having an existing special health care need. Bivariate and multivariate analyses were used to assess how race and ethnicity are related to measures of access and utilization, such as usual source of care, missed care, and use of physician and hospital services.

RESULTS

Our analyses show that among children with special health care needs, minorities were more likely than white children to be without health insurance coverage (13.2% vs 10.3%; P <.01), to be without usual source of care (6.7% vs 4.3%; P <.01), and to report inability to get needed medical care (3.9% vs 2.8%; P <.05). Also, white children with special health care needs were more likely than their minority counterparts to have used physician services (88.6 vs 85.0; P <.01); however, minority children with special health care needs were more likely to have been hospitalized during the past year (7.6% vs 6.3%; P < 0.5). After adjustments for confounding variables (income, insurance coverage, health status, and other variables), racial and ethnic differences in access and utilization were attenuated but remained significant for several measures (without a usual source of care, receipt of care outside of a doctor's office or HMO, no regular clinician, no doctor contacts in past year, and volume of doctor contacts). Gaps in access were more frequent and generally larger for Hispanic children with special health care needs.

CONCLUSIONS

Our analysis indicates that access and utilization disparities remain between white and minority children with special health care needs, with Hispanic children experiencing especially disparate care.

Access to care, unmet health needs, and poverty status among children with and without chronic conditions

OBJECTIVES

To compare insurance coverage, access to care, and unmet health needs of children with and without chronic conditions in a national probability sample of the US population and to examine the role of poverty status in any demonstrated differences between the 2 groups.

DESIGN

We analyzed parent-report data on children 0-17 years old from the 1994 National Health Interview Survey Disability Supplement (NHIS-D) and from the health insurance and access to care files of the 1994 Family Resources Supplement to the NHIS. In the NHIS-D, 4452 (14.8%) of the 30032 children were identified as having a chronic condition by a noncategorical method. We compared insurance coverage, access to care, and unmet needs of children with and without conditions overall and also compared them within 3 different income levels relative to the national poverty index: 1) below, 2) within 100%-200%, and 3) >200% above poverty level.

RESULTS

In bivariate analyses, children with chronic conditions were more likely to be covered by some type of health insurance (odds ratio [OR], 1.3) and to have a usual provider both for medical ("sick") care (OR, 1.4) and for routine or preventive care (OR, 1.4). They also were more likely to have the same provider for medical care and routine or preventive care (OR, 1.2) and to have seen their health care provider in the last year (OR, 1.8) than children without chronic conditions (all P <.0001). Nonetheless, children with chronic conditions were twice as likely to have had at least 1 unmet need from a list of 4 services that included dental care, prescription medications, eyeglasses, and mental health services (OR, 2.0). They also were more likely to have more than 1 unmet need from the list (OR, 3.1), to have been unable to get needed medical care (OR, 3.1), and to have delayed obtaining medical care because of worry about its cost (OR, 1.8). Children with chronic conditions were at greater risk for unmet needs than were children without conditions across all income levels. The magnitude of the disparity between the groups increased with family income level. Differences persisted even after controlling for sociodemographic variables and insurance status.

CONCLUSION

Despite higher levels of insurance coverage and greater access to regular providers of medical and routine care compared with healthy peers, children with chronic conditions are reported by their parents to be less likely than other children to receive the full range of needed health services. The magnitudes of the differences are small, yet the pattern of disadvantage in meeting health care needs among children with conditions compared with healthy peers is consistent across many different variables and it exists across income levels.

Parental employment and health insurance coverage among school-aged children with special health care needs

OBJECTIVES

This study examined parental employment and health insurance coverage among children with and without special health care needs. Special needs were defined as conditions likely to require a high amount of parental care, potentially affecting parental employment.

METHODS

Data from the 1994 National Health Interview Survey were analyzed for 21,415 children aged 5 to 17 years, including 1604 children with special needs. Logistic regression was used to estimate the effect of special needs on the odds of full-time parental employment and on the odds of a child's being uninsured, having Medicaid, or having employer-sponsored insurance.

RESULTS

Parents of children with special needs had less full-time employment. Their children had lower odds of having employer-sponsored insurance (adjusted odds ratio [OR] = 0.7) than other children. Children with special needs had greater odds of Medicaid coverage (adjusted OR = 2.3-5.1, depending on family income). Children with and without special needs were equally likely to be uninsured.

CONCLUSIONS

Lower full-time employment among parents of children with special needs contributes to the children's being less likely to have employer-sponsored health insurance. Medicaid covers many children with special needs, but many others remain uninsured.

Barriers to asthma care in urban children: parent perspectives

BACKGROUND

Despite improved treatment regimens for asthma, the prevalence and morbidity from asthma are increasing, especially among underserved, minority children.

OBJECTIVE

The purpose of this study was to identify barriers to the treatment of asthma among urban, minority children as perceived by parents.

METHODS

Parents were recruited from 4 schools located in low-income, urban areas with high rates of asthma hospitalizations. Focus groups involving parents of children 5 to 12 years old with asthma were conducted using a standardized questionnaire. Parents' comments were analyzed to identify barriers, and 3 independent raters coded parents' comments to assess reliability of interpretation.

RESULTS

Forty parents who represented 47 children participated in the focus groups. All parents described their racial background as black. Parents' average age was 36.8 years, 92% were females, 70% were nonmarried, and 38% had less than a high school education. Forty-five percent of children had intermittent or mild asthma and 55% had moderate to severe asthma. The most frequent types of barriers identified by parents were patient or family characteristics (43%), followed by environmental (28%), health care provider (18%), and health care system (11%). Parents were specifically concerned about the use, safety and long-term complications of medications, the impact of limitation of exercise on their child's quality of life, and their own quality of life.

CONCLUSIONS

In contrast with the widespread beliefs that access to medical care, health insurance, and continuity of care are the major barriers to quality asthma care, the barriers most frequently reported by parents were related to patient and family characteristics, health beliefs, or to their social and physical environment. To improve asthma management and health outcomes for urban, minority children with asthma, it is critical to tailor education about asthma and its treatment, and address quality of life issues for both children and parents.

Hospital and emergency department use by young low-income children

BACKGROUND

Limited data are available concerning determinants of health care service usage by low-income young children.

OBJECTIVES

To explore predictors of hospitalization and emergency department (ED) use by young children of low-income families by using the Aday and Andersen Access Framework.

METHODS

Low-income women (n = 474) with a child younger than 6 years completed a structured face-to-face interview at human service offices or Women, Infants, and Children (WIC) clinics in four central Ohio counties. Women were considered low-income if they or their child were Medicaid eligible or uninsured. Data were collected for both the mother and the index child on sociodemographic status, health services use, health status, and access to care.

RESULTS

Fifteen percent of the children had been hospitalized the previous year, and half had an ED visit. Hospitalization was significantly related to maternal hospitalization the previous year (OR = 2.5), child age younger than 1 year old (OR = 2.1) and more than two chronic conditions (OR = 2.2). Maternal ED usage in the last year (OR = 2.2), Medicaid fee for service plan (OR = 1.7), and rural residence (OR = 2.0) were predictive of ED use.

CONCLUSIONS

Predisposing characteristics (maternal hospital/ED use) were predictive of both hospitalization and ED use by the index child. Enabling characteristics (fee-for-service Medicaid plan, rurality) were only predictive of ED use, and need characteristics (child's health) were only predictive of hospitalization. Further research to explore linkages between maternal and child use of health care services as well as the effect of changes in health care access, managed care, and other innovations on hospitalization and ED use in young, low-income children is recommended.

Measuring quality of care for vulnerable children: challenges and conceptualization of a pediatric outcome measure of quality

This article addresses conceptual and practical issues in the assessment of pediatric health care quality, outlines a conceptual model for measuring quality, and describes ongoing research to validate an outcome measure of health care quality for vulnerable children. Pediatric quality measurement is distinct from that for adults due to development, dependence, differential epidemiology, demographic factors, and differences between the child and adult health services systems. A noncategorical approach to quality measurement, rather than one based on illness status or specific condition, is necessary to adequately measure quality for the majority of children, both healthy and ill. One promising noncategorical measure of pediatric health care quality is health outcome, specifically health-related quality of life (HRQOL). The Pediatric Quality of Life Inventory (PedsQL), a brief, practical, reliable, valid, generic pediatric HRQOL measure, is a suitable candidate measure. Ongoing research to validate the PedsQL as an outcome measure of health care quality is described.

Access to health care for children with special health care needs

OBJECTIVE

To assess the role health insurance plays in influencing access to care and use of services by children with special health care needs.

METHODS

We analyzed data on 57 553 children younger than 18 years old included in the 1994-1995 National Health Interview Survey on Disability. The survey obtained information on special health care needs, insurance status, and access to and use of health services. Bivariate and multivariate analyses were used to assess the association of insurance with several measures of access and utilization, including usual source of care, site of usual care, missed or delayed care, and use of ambulatory physician services.

RESULTS

Using the federal Maternal and Child Health Bureau definition of children with special health care needs, we estimate that 18% of US children under 18 years old had an existing special health care need in 1994-1995. An estimated 89% of these children had some form of health insurance coverage, most often private health insurance. Insured children were more likely than uninsured children to have a usual source of care (96.9% vs 79.2%). Among those with a usual source of care, insured children were more likely than uninsured children to have an identified regular clinician (87. 6% vs 80.7%). Insured children were less likely to report unmet health needs, including medical care (2.2% vs 10.5%), dental care (6. 1% vs 23.9%), prescriptions, and/or eyeglasses (3.1% vs 12.3%), and mental health care (.9% vs 3.4%). Insured children were also more likely to have a physician contact in the past year (89.3% vs 73.6%) and have more physician contacts on an annual basis (8.5 vs 4.1 contacts). Unexpectedly, no differences were found between insured and uninsured children in availability of after hours medical care (evenings and weekends) or satisfaction with care. We also found some modest differences in access between publicly and privately insured children. Privately insured children were more likely to have a usual source of care (97.6% vs 95.3%) and a regular clinician (91.0% vs 81.1%). Privately insured children were also less likely to report dissatisfaction with care at their usual site of care (14. 9% vs 21.0%) and have access to care on evenings and weekends (6.8% vs 13.4%). No substantial differences were found between privately and publicly insured children in prevalence of unmet health needs or delays in obtaining care due to cost.

CONCLUSIONS

This study illustrates the importance of health insurance for children with special health care needs. Continued efforts are needed to ensure that all children with special health care needs have insurance and that remaining access and utilization barriers for currently insured children with special health care needs are also addressed.

Development of a Chinese chronic illness-related stress inventory for primary care

This study evaluates the construct validity and internal consistency of a Chronic Illness-Related Stress Inventory (CRSI) for primary care Chinese patients and studies the relationship between chronic illness-related stress and sociodemographic characteristics and indices of disease severity. A total of 301 patients were interviewed using a structured questionnaire. The responses to the CRSI were divided into a frequency scale and a severity scale. Six factors including physical integrity and discomfort, psychosocial function and economic burdens, self-fulfillment and daily life, sexual function, self-esteem, and diet limitations were obtained for each CRSI scale. Except for the last factor, all other factors and the scale as a whole for both scales have a Cronbach alpha of > 0.90. The results of the convergent and discriminant validity analysis were promising. In addition, chronic illness-related stress was related to insurance status and the self-perceived severity of disease.

Health care utilization by children with chronic illnesses: a comparison of medicaid and employer-insured managed care

OBJECTIVES

This study compared utilization of health care services by children with chronic conditions who were insured by either Medicaid or an employer group in 1992 and 1993. Five chronic conditions were selected to illustrate patterns of service use: asthma, attention deficit disorder, diabetes, epilepsy, and sickle cell anemia.

METHODOLOGY

Administrative databases were used to develop estimates of health services utilization for children <18 years of age with the five selected conditions, who had been enrolled for at least 6 continuous months. All claims for a child identified with one of these five conditions were included in the analysis, including claims for diagnoses and procedures not directly related to the primary diagnosis. Estimates were derived for eight services (eg, hospital admissions, emergency department (ED), home health). Data were used from two Independent Practice Association model health plans in two states. Differences across the states were controlled by selecting one Medicaid and one employer-insured program from each of the two plans in both states. Regional variation was controlled for because both health plans were located in one geographical region. In each case, physicians were paid on a fee-for-service basis, with generally open access to specialists rather than primary care gatekeeper models of delivery: t tests were used to compare service use rates between Medicaid and employer-insured populations.

RESULTS

A total of 8668 children across all health plan groups had at least one of the selected conditions. Because Medicaid enrolled-children tended to be younger, analyses were adjusted for age. In both systems, a greater percentage of Medicaid children had these five study conditions (5%) compared with employer-insured children (3%), suggesting that the Medicaid population was sicker. Mean length of enrollment during the 2-year study was longer for children in employer-insured programs. Children with chronic conditions enrolled in Medicaid managed care generally used services at a higher rate compared with children with similar conditions enrolled in employer-insured managed care. The extent of the increased use varied by condition, by service type, and by plan. Children with any of the chronic conditions studied had from 2 to almost 5 times more ED visits if they were enrolled in Medicaid than if they were enrolled in employer-based managed care, depending on the specific condition. In one of the two plans, Medicaid-enrolled children had more outpatient services, laboratory services, and radiography services than their counterparts in employer-based managed care. The same pattern of use was found for home health services (except for children with diabetes) and for office visits (except for children with sickle cell). The results show higher use of all services by children with asthma and diabetes in Medicaid managed care compared with employer-based managed care. In contrast, the pattern is mixed for children with epilepsy and sickle cell. The sample size of children with these conditions was smaller than with the three other conditions, which may account, in part, for a varied pattern of results. The pattern of use for attention deficit hyperactivity disorder (ADHD) was generally different from the other conditions. Children with ADHD in employer-based managed care had more hospital admissions, hospital days, and office visits than their counterparts in Medicaid managed care. In contrast, Medicaid-enrolled children with ADHD had more ED visits, laboratory services, outpatient hospital visits, and radiography services. Other than ED visits, the differences in service use between Medicaid and employer-insured children with ADHD were minimal. Of note, the pattern for ADHD is the same for most services for Plans A and B (excluding home health visits). This utilization pattern may reflect service use for comorbid conditions. Part of this difference may be explained by differences in Medicaid e

Monitoring the consequences of uninsurance: a review of methodologies

The proportion of the United States population without health insurance continues to grow. How will this affect the health of the nation? Prior research suggests that the uninsured are at risk for poor health outcomes. They use fewer medical services and have higher mortality rates than do insured persons. The episodic nature of uninsurance and its prevalence among disadvantaged groups makes it difficult to ascertain the health effects of uninsurance. The goal of this review is to assist researchers and policy makers in choosing methodologies to assess the effects of uninsurance. It provides a compendium of methods that have been used to examine the health consequences of uninsurance, the populations in which these methods have been used, and the strengths and weaknesses of different approaches. The review highlights the need for more longitudinal studies that focus on community-based samples of the uninsured.

An explanatory model of the dental care utilization of low-income children

OBJECTIVES

Factors related to the utilization of dental care by 5- to 11-year-old children from low-income households were investigated using a comprehensive multivariate model that assessed the contribution of structure, history, cognition, and expectations. The influence of dentist-patient interactions, psychosocial and health beliefs, particularly fear of the dentist, on utilization were investigated.

METHODS

Children were chosen randomly from public schools, and 895 mothers were surveyed and their children were interviewed in the home. Utilization was studied during the 1991-1992 school year, including a 6-month follow-up period after the interview.

RESULTS

The overall utilization rate was 63.2%, and the rate for nonemergent (preventive) visits was 59.9%. Utilization was unrelated to actual oral health status. Race and years the guardian lived in the United States were predictive of an episode of care. Preventive medical visits and perceived need were strong predictors of a visit to the dentist, as were beliefs in the efficacy of dental care. Mothers who were satisfied with their own care and oral health and whose children were covered by insurance were more likely to utilize children's dental care. In contrast, child dental fear and absences from school for family problems were associated with lower rates of utilization.

CONCLUSIONS

Mutable factors that govern the use of care in this population were identified. These findings have implications for the design of dental care delivery systems for children and their families.

Health insurance and access to primary care for children

BACKGROUND

Numerous studies have demonstrated that insurance status influences the amount of ambulatory care received by children, but few have assessed the role of insurance as a determinant of children's access to primary care. We studied the effect of health insurance on children's access to primary care.

METHODS

We analyzed a sample of 49,367 children under 18 years of age from the 1993-1994 National Health Interview Survey, a nationwide household survey. The overall rate of response was 86.5 percent. The survey included questions on insurance coverage and access to primary care.

RESULTS

An estimated 13 percent of U.S. children did not have health insurance in 1993-1994. Uninsured children were less likely than insured children to have a usual source of care (75.9 percent vs. 96.2 percent, P<0.001). Among those with a usual source of care, uninsured children were more likely than insured children to have no regular physician (24.3 percent vs. 13.8 percent, P<0.001), to be without access to medical care after normal business hours (11.8 percent vs. 7.1 percent, P<0.001), and to have families that were dissatisfied with at least one aspect of their care (19.6 percent vs. 14.0 percent, P=0.01). Uninsured children were more likely than insured children to have gone without needed medical, dental, or other health care (22.2 percent vs. 6.1 percent, P<0.001). Uninsured children were also less likely than insured children to have had contact with a physician during the previous year (67.4 percent vs. 83.8 percent, P<0.001). All differences remained significant after we controlled for potential confounders using linear and logistic regression.

CONCLUSIONS

Among children, having health insurance is strongly associated with access to primary care. The new children's health insurance program enacted as part of the Balanced Budget Act of 1997 may substantially improve access to and use of primary care by children.

Socioeconomic inequity in health care: a study of services utilization in Curaçao

The aim of this study is to examine whether there is socioeconomic equity in health care utilization in Curaçao, Netherlands Antilles. We explore how educational level is related to utilization of GPs, specialists, hospitals; dentists and physiotherapists, taking into account the effects of sex, age and inequalities in health. The study also examines whether these relationships vary according to the unit of analysis: probability (or incidence) of services use versus overall volume of contacts. The data were derived from the Curaçao Health Study, a health interview survey among a random sample (N = 2248) of the non-institutionalized population aged 18 and over. The results indicate that there is socioeconomic inequity in the probability of health care utilization in Curaçao. People with a higher educational level are more likely to consult a specialist, dentist or physiotherapist, and are also more likely to be hospitalized. This is not only the case when the mediating effects of socioeconomic inequalities in health (need) are taken into account, but also before adjustment for health inequalities. In other words: there appears to be both vertical inequity (i.e. greater needs for services are not met by greater use) and horizontal inequity (i.e. similar needs for care are not met by similar levels of services use). The observed inequalities in use of specialists and hospitals contrast with findings from international research. The volume of health services use (i.e. the numbers of consultations) appears to be hardly connected with a person's position in the SES hierarchy; only dental services are used more extensively by higher educated individuals.

Socio-economic status and visits to physicians by adults in Ontario, Canada

OBJECTIVES

To examine the association between socio-economic status, need for medical care and visits to physicians in a universal health insurance system.

METHODS

Cross-sectional analysis of the 1990 Ontario Health Survey, a population-based survey utilizing a multi-stage, randomized cluster sample. The analysis considered only those respondents who were 16 years of age or older from the province of Ontario, Canada: 21,272 males and 24,738 females.

RESULTS

There was no difference by education or income in persons having made at least one visit to a general practitioner in the previous year. High income persons were less likely to have made six or more visits to a general practitioner--odds ratio (OR) = 0.67, 95% CI = 0.52, 0.87 for men; OR = 0.66, 95% CI = 0.58, 0.75 for women--but more likely to have made at least one visit to a specialist--OR = 1.42, 95% CI = 1.15, 1.76 for men; OR = 1.25, 95% CI = 1.07, 1.45 for women. A person's need for medical care was the most important determinant of a physician visit.

CONCLUSIONS

Self-reported visits to general practitioners in Canada are strongly influenced by a person's need for medical care and are appropriately related to socio-economic status. However, there is a residual association between higher socio-economic levels and greater use of specialist services.

The School Enrollment-Based Health Insurance program: socioeconomic factors in enrollees' use of health services

OBJECTIVES

The School Enrollment-Based Health Insurance program is designed to reduce financial barriers to children's health care use. This study sought to determine if any socioeconomic measures differed between enrollees with at least one health care encounter and those with no encounters.

METHODS

Logistic regression was used to assess the impact of various predictors on the odds that a child would use health care services.

RESULTS

Children receiving free insurance premiums were less likely to use health care than those receiving partial subsidy. African-American and Hispanic children were less likely than Whites to use health care. Age, sex, and months enrolled also influenced the likelihood of health care use.

CONCLUSIONS

Financial and non-financial factors must be considered when developing children's health care programs.

Help-seeking preceding mental health clinic intake among African-American, Latino, and Caucasian youths

OBJECTIVE

Pathways into child mental health clinics were studied to test this hypothesis: Prior to contacting clinics for their child's problems, African-American and Latino families are less likely than Caucasian families to seek help from agencies and professionals (and more likely to contact family and community sources).

METHOD

Regression analyses, applied to a sample of 192 clinic-admitted families, assessed the impact of ethnicity and income, child gender and age, and parent perceptions of child problem severity and likely treatment benefit, on preclinic help-seeking.

RESULTS

As predicted, African-American and Latino families, compared with Caucasian families, sought help from professionals and agencies much less often, as a first step and as a percentage of all their preclinic help-seeking. With income, age, gender, and parent perceptions in the model, both African-American and Latino families were 0.37 as likely as Caucasian families to seek initial help from a professional or agency.

CONCLUSION

Although many minority youths are admitted to mental health clinics, seeking help from professionals may not have been their parents' preference. The apparent reluctance of minority parents carries implications for clinical intervention and alliance formation with minority group families and for the design and evaluation of ethnic community outreach programs.

People with mobility impairments in the United States today and in 2010

This article presents a study undertaken to develop a population profile of people with mobility impairments in the U.S.A. today and to estimate the profile of people with mobility impairments in the year 2010. The profile was developed under contract to the U.S. Architectural and Transportation Barriers Compliance Board (Access Board) as part of a project to examine technical requirements for ramp slope and length. The profile was used to establish a representative (both today and in the future) sampling frame for human subjects in the current project, as well as to guide the Access Board in developing accessibility guidelines in the future. The present article highlights findings concerning mobility impairments in the population today and trends likely to influence the future prevalence of such impairments. The findings have implications for accessibility requirements and disability policy in general.

A research agenda for health education among underserved populations

This article summarizes the outcome of health education efforts among populations that, due to their cultural heritage, have received limited services. The literature reviewed shows that programs found to be effective in one population cannot be assumed to be equally effective with a different population. An argument is made for the design of culturally appropriate and group-specific interventions which would properly serve the various underserved populations. Research needs to be conducted to identify appropriate approaches and intervention strategies, as well as the group-specific sociopsychological characteristics (attitudes, norms, values, expectancies) that are related to health-damaging and protective behaviors.
